Quran 7:87 from Surah Al-A'raaf on Divine Marvels.
وَإِن كَانَ طَآئِفَةٞ مِّنكُمۡ ءَامَنُواْ بِٱلَّذِيٓ أُرۡسِلۡتُ بِهِۦ وَطَآئِفَةٞ لَّمۡ يُؤۡمِنُواْ فَٱصۡبِرُواْ حَتَّىٰ يَحۡكُمَ ٱللَّهُ بَيۡنَنَاۚ وَهُوَ خَيۡرُ ٱلۡحَٰكِمِينَ
English translation: And if (there) is a group among you (who has) believed in that which I have been sent with [it] and a group not they believe then be patient until judges Allah between us And He (is the) Best (of) [the] Judges
Transliteration: wa-in kana taifatun minkum amanu bi-alladhi ur'sil'tu bihi wataifatun lam yu'minu fa-is'biru hatta yahkuma al-lahu baynana wahuwa khayru al-hakimina
